Sound familiar?
The day-to-day headaches window and door fitters tell us about most — and how Gaffer fixes them.
Quotes take a week to write up
Homeowners get three quotes and go with whoever replies first. Send a tidy itemised quote for windows and doors from your phone before you leave the survey.
Snagging drags the job out
Missing trims, a sticky handle, a sealant touch-up — and no clear list. Log snags with photos on the final visit so nothing gets forgotten and the customer signs off happy.
